BENJAMIN ROBERTS, or INDIANAPOLIS, INDIANA.V

SMOKE-CONDENSER.

SPECIFICATION forming part of Leners Patent No. 382,665, dated May e, 188s.--

Application filed December' 13, 1887. Serial No. 257,812. (-No model.)

To' all whom, it may concern:

-Be it known that I, BENJAMIN Renners, a citizen of the United States, residing at Indianapolis, in the county of Marion and'State of Indiana, have invented certain new and useful Improvements in Smoke-Oondensers, of which the following is a specification.

My present invention consists in various improvements in the construction of smokecondensers, relating .especially to the Ysmokecondensers shown in my Letters Patent-No. 360,052, dated March 29, 1887, and No. 371,365, dated October 11, 1887, by the use of which said condenser is rendered more efficient and its operation more perfect, as will be hereinafter more particularly set forth.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1 is a central vertical section of the smoke-condenser and its adjacent parts arranged in'position in connection with a furnace and boiler, on 'the dottedline 1 1 in Fig. 2; Fig. 2, a horizontal section, looking downwardly from the dotted line 2 2 in Fig. l; Fig. 3, a cross-section on the dotted line 3 3 in Fig. 1, and Fig. et a view showing the faneasing-on the rear end of the breeching in end elevation.

In said drawings, the portions marked A represent a furnace and boiler; B, the breeching or conduit leading from said furnace to the condenser; C, said condenser, and D a blast-fan mounted in said breeching.

The furnace and boiler A are of any ordinary oonstruction, and the smoke-condenser G is the identical smoke-condenser shown in my Letters Patent No.y 371,365, above referred to, and these several parts, therefore, need no specialdescription, except incidentally in describing the particular features constituting my present invention.

The breeching or conduit B is substantially similar to that shown in my Letters Patent above referred to, and is connected tothe furnace by a smoke-chamber, A', in the throat of which is mounted an ordinary damper, a, arranged to be "operated by a crank-shaft, a', as will be readily understood. Over ,the mouth of the smoke-chamber I arrange within the breeching B a hood, B', with an'open front end and a closed rear end, as shown, the top of saidv hood being extended some distance beyond said mouth, and-its sides extended d own, thus completely inclosing said mouth,except at the front. On the rear end of the breeching I form or attachy a blast-fan casing,the en-v trance from which into said breechin'g is arranged nearits bottom. Within said casing-I mount an ordinary blast-fan, D, arranged to bei driven by any convenient power. The casing is provided ,with the usual airinlet holes .in its ends, and with adjustable cut-oft' valves d, to regulate the quantity of air admitted.

The operation of my said invention isvr as follows: rThe several parts being `put into active operation, the blast from the blast-fan D operates in passing over the hoods B'the rear portions of which are formed slanting from the fio'or of the breeching or conduit to their topstoward the condenser to create a strong draft, which may be regulated bythe cut-off Valves d, and the smoke coming from the furnace is directed by said hoods forward toward the condenser in a line with the draft thus created, and at the same tilne'any of said., draft is prevented from passing down into the smokechambers and interfering with the draft of the furnaces. `The smoke intermingling with the atmosphere from outside, thus introduced by the blast-fan, immediately upon'it-s entrance vinto the conduit, is partially condensed or absorbed into said air in the same manner that it would be if allowed to escape to the Vouter air; or, in other words, the carbonio gasesare.

taken up or diluted by the natural atmosphere, with which they are thus brought into Contact, and then the whole passes into the condenser C, where it is inet'with a shower'of water from the sprinkling device C', which is connected with the water-supply pipe C, and

thus thoroughly condensed or absorbed andv carried off through the out-letat thefbottom of said condenser into the sewer or other con duit, in the same manner as described in my tion,whatI claim as new, and desire to secure by Letters Patent, isi-- 1. The combination of a furnace, a smoke- Ice condenser, a conduit arranged to conduct the smoke from said furnace to said condenser, and means for introducing a blast of air from the outside into the apparatus behind the smoke-entrance, substantially as shown and described.

2. The combination of a smoke-condenser, a furnace, a breeching or conduit connecting them, and a blast-fan arranged at the rear end of said conduit behind said furnace, substantrialiy as set forth.

3. The combination of the furnace, condenser, conduit connecting them, a biastfan arranged at the rear end of said conduit, and a hood arranged Within said conduit over the smoke-entrance thereto, substantiallyas set forth.

4. The combination of the furnace, the condenser, tlie conduit or breeching connecting them, a damper arranged in the path of the 2o smoke, an imperforate hood over the smokeentrance to the conduit, and the air-blast, substantially as set forth.

5. The combination of the furnace, condenser, conduit connecting said furnace .and 25 condenser, an im perforate hood arranged with in said conduit over the smoke entrance thereto, and means for introducing a blast of air behind said smoke-entrance, substantially as described, and for the purposes specified. 3o

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 7th day of December, A. D. 1887.
